A star mass

A star mass is a group of stars that stay together thanks to mutual gravitational attraction. In the image we see a double star mass made of very young stars in the Big Cloud of Magellan, one of our satellite galaxies. Furthermore we notice that the double mass is surrounded by a blue filigree structure made up by diffused gas, which astronomers identify as the remains of a supernova. Millions of years ago a star from the main mass probably exploded as a supernova leaving behind a trail of detritus. Astronomers believe that the birth of new stars is brought on by the death of nearby stars: colliding with a stable cold cloud, in fact the wave caused by an explosion could trigger a first compression of material which would then begin to collapse under its own mass.
